Abstract: A display apparatus capable of being touched plural times by a single user or being used by a plurality of users is provided. The display apparatus includes: a display; a sensor sensing a user touch on the display; and a processor configured to execute a writing function corresponding to a first touch when the first touch is sensed through the sensor and executing a function corresponding to a second touch of a user at a coordinate value at which the second touch is sensed in response to the second touch when the second touch is sensed in a predetermined range of the first touch based on a coordinate value at which the first touch is sensed during a period in which the first touch is input.
